Expand description

EVM configuration.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§chain_id: u64

Chain ID of the EVM, it will be compared to the transaction’s Chain ID. Chain ID is introduced EIP-155

§spec: SPEC

Specification for EVM represent the hardfork.

§limit_contract_code_size: Option<usize>

If some it will effects EIP-170: Contract code size limit. Useful to increase this because of tests. By default it is 0x6000 (~25kb).

§disable_nonce_check: bool

Skips the nonce validation against the account’s nonce.
